Question

I am trying to create a multidimenssional array like this

var myArray = new Array();
          var test = new Array(1, 100,200,2);
        $.each(test, function(index, val) {

            myArray['value'].push(val);
            myArray['index'].push(index);
        });

but console.log(myArray) shows me no values;

Answer 1

Use an object literal instead of an array:

var myHash= {
    value: [],
    index: []
},
test = [1, 100,200,2];

$.each(test, function(index, val) {
    myHash['value'].push(val);
    myHash['index'].push(index);
});

You shouldn’t use arrays as associative arrays. Arrays are accessed by 0-based index and you shouldn’t assign arbitrary properties to arrays.
